摘要
研制了一种以脲和硫脲为主体的固体电解质，其室温电导率可达到６．８４×１０－３Ｓ·ｃｍ－１，分析了影响该电解质电导率的因素．初步确定该物质为一种不定型固熔体，导电机理是硫脲转化为硫氰酸铵。
New solid electrolytes based on urea and thiourea have been synthesized. Their ionic conductivity detected by electronic conductivity instrument is higher than 6 84×10 -3 S\5cm -1 at room temperature. The main factors influencing the ionic conductivity are analyzed. These are amorphous solid solution. The thiourea changes to ammonium thiocyanate, which can ionize and conduct in the solid electrolyte.
